MHDT Havana DAC - Page 164

post #2446 of 2665

If anybody is curious ... here is a shot of the new Stockholm v2 DAC internals. 

 

This is the board where they have bypassed the PCM56K's internal OPAMP section:

Cheers.

I see already some Black Gate and V-Caps there :etysmile:...Oscon's are the best for the digital stage section, no doubt.

 

@Joel,

 

when you start a modding with this beauty? :D

Hi!

I have a question. May I use 0,10uF caps as a input capacitors? I have some Audyn TC 

As a output capacitors they sound great (0,47) ! 

post #2449 of 2665

Sure you can. However if you already got Audyn TC on output I would try more neutral caps elsewhere too avoid a too typical result but Audyn TC are great ones so you would not be wrong anyway.

I am doing some more upgrades on my Havana and I am ordering some Schottky diodes from PartsConnexion. I have read through this thread several times but can't seem to nail down the exact type to order. They have several types to choose from:

 

1A 600V

4A 600V

5A 1200V

6A 600V

10A 600V

10A 1200V

 

Price ranges from $1.50 to $24.95 each. (I hope the cheaper ones are the best!)

 

Which of these is the correct spec? I need 8 of them.

I used 600V 2A from Mouser:

That value is referenced as viable somewhere in this thread.  Works for me.

Thanks...

 

My vote would go to Rike Audio S-Caps.  The depth of detail and separation and dynamics are incredible, and the tone is very natural as well.  The details do not come in the form of harsh, overly-highlighted highs, as some might fear from such a description.  It is a very well-balanced cap.  Exactly the injection the stock Havana needs, in my opinion.

post #2453 of 2665

Thanks for the Schottky info. Will those Rikes fit into the Havana? They look huge!

post #2454 of 2665

0.47 uF should fit.  They are smaller in diameter and length than V-Cap CuTF, which many of us have used.

post #2455 of 2665

I was thinking of the 2.2uf for C33 and C35. They are 40mm X 40mm X 26mm.

You can use 0.47 uF instead of 2.2 uF with no ill effects.  I believe it was Robeeert1 who discovered this with V-Cap CuTF so several of us went with it.  Sounds great!

0,47uF for outputs will do the great job... smily_headphones1.gif
No higher values are needed in the case of Havana

I agree, Eugene.  S-Caps are very neutral and create the feeling of capacitors disappearance (without caps)...Instrument and voice tonal colours are very slightly enhanced over no cap. I think, they are the best for Havana in this price category. :smile: They works very well in this DAC! If I had more money, would have changed all film capacitors with Duelund Cast PIO. If Rike sounds so good, I imagine how would sound Duelund. Would be close to perfection, IMHO..

 

 ... however, Rike & V-Cap CuTF = audiophile delight. :ksc75smile:

For some reason my Havana is giving me the red light and blue light at power up and won't go beyond that. It has been fine in the past. Can anyone tell me what the red indicates? Digital signal or electrical issue?

post #2460 of 2665

Turns out it was a digital issue. One of the contacts on my spdif cable came loose. Soldered it back on plugged in and green light is back!
